In Sergio's "Open Swiss" tournament, Myrddin v Jumbo, the above position was reached. Myrddin found the best move, which I'm sure is easy for computers (although could prove challenging for engines <2250), and probably decently strong humans as well. The game ended in a draw, but I'm not convinced that the best move guarantees a draw. Can somebody with much better engines and faster computers check it out for me, please?

Re: Test Position
Here's the full game. The final position after the resulting king hunt is amusing.

Re: Test Position
Hello John, Kaissa thinks Black has a sure draw after you take the rook, but nothing much more than that. So it seems that Jumbo scores are a bit Jumbo large?

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.
